I would suspect you are fairly close to the answer. A throttle by wire that simply directly translated potentiometer values to actuator locations (throttle grip position to throttle plate position) would not have this problem.
However, the throttle grip sensor sends information to a computer, and that computer decides what to do with it. That decision is likely the problem. Riders are finding themselves in a computer determined throttle position that results in low takeoff power.
The good news is that this can be corrected with a simple remapping. The bad news is I doubt it will be done by the manufacturer. After market may step in though.

so if the engine is bogging down and rpm not increase then it is like a dog chasing its tail.

I've experienced this on my 2014 King at least twice now. It seems to happen when the bike gets hot and I am sitting at a light. I don't think it has anything to do with the gearing, etc. It's as if there is a spot on the throttle that chokes the bike out. You can't slowly increase the throttle or the bike will stall. You need to blip it get the rpms up and then you are good. Now that I am hearing other people are having this problem it makes me think there is an actual problem with the throttle map or something. It does seem to idle really low. It should be pretty easy to test. Ride the bike pretty hard and get it hot. Get off the street and put the bike in N. Sit there for a couple minutes like you are waiting for a train to pass. Put the bike in gear and slowly give it throttle. It will act like it's going to stall, blip the throttle to get the rpms up and then it's fine. Is it possible that the bike is going into 'parade mode' and shutting down the rear jug?..then when you hit the throttle it lags and takes a half second for it to fire up? With this HO motor putting out more HP it must be putting out more heat?

Question on the tpms. Do they supply a added weight to be put on the wheels to offset the weight of the sensor? I know Pressure Pro supplies 1/2 oz weight to be put on opposite of the valve stem while the sensor is on to keep the tire wheel in balance.

sounds like you are going into heat management, rear cyclinder fuel off, blipping turns it on again.

Man, you guys woulda really peed down your legs if you ever road some of the old pans and shovels that bogged down a little from stop...back in the day, we didn't have the interweb...figgered it was part of the deal. Hell, we could have REALLY been whining about that! Dern it!
